IMPROVED APPARATUS FOR CARBURETING AIR.

Specification forming part of Letters Patent'No. 59,474, dated November 6, 1866.

To all whom it may concern Be it known that I, LEVI STEVENS, of Fitchburg, in the county of Worcester and State of Massachusetts, have invented an Improved Air-Oarbureting Apparatus; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 denotes a vertical section, and Fig. 2 a side elevation, of such apparatus.

In the said drawings, E denotes a cylindrical vessel provided with a tubular extension, F, which runs from and opens through the top of the vessel E, and at its upper end is provided with a discharge opening or pipe, 0. The vessel E surmounts a tank, A, and is placed within a cistern or vessel, B, to contain water, W, and an aerometer or gasometer bell, G. This latter, open at its lower end, floats in the water and surrounds the extension F, and communicates with the interior of the vessel E by means of one or more vertical pipes, 0 0, extending from the top of such vessel E.

Within the vessel E, and at its lower part, is a chamber, 0, arranged concentrically with the said vessel, andwith an annular space, 1), between them. A series of holes, a a, leads out of the lower part of the sides of the chamber O, and such chamber, at its bottom, has a pipe, k, extending from it into the chamber M of an elevator, K.

The said chamber M is disposed against the external surfaces of the tank A and cistern B,

manner as shown at l in Fig. 1.

Furthermore, there is a s onge holding chamber or space, D, arranger directly over the chamber 0 and in the vessel E, and formed in part by a partition, H, carried horizontally across the vessel. The said partition is perforated with numerous holes at or about its center. The part E of the vessel E, which is over the said partition, constitutes a chamber for the reception of the gasoline or hydrocarbon fluid, which enters it by a pipe, g, leading from a spout, 19, situated in the elevatorchamber.

A pipe, 3, from an air-forcing apparatus,

serves to discharge air into the chamber 0, and, if desirable, there may be another such pipe to discharge air into the space E. I

The elevator, K consists of a series of buck ets, q q q, affixed, at equal distances apart, to an endless chain, 1", which works around two wheels, on n, arranged as representedin the drawings. By revolving the upper of said pulleys by power suitably applied to the shaft 0, the gasoline may be taken up from the chamber M, and be discharged into the spout p, from whence it will flow through the pipe 9 and be discharged upon the central part of the partition H. The liquid diffused over the plate H will flow through it and the sponge packing t of the chamber D, and thence into the space I), from whence it will pass into the chamber G. From this latter chamber the unevaporated liquid will be discharged by the pipe k, and again enter the elevator-chamber M. The air driven into the chamber 0 will move in directions contrary to those as'above described as taken by the gasoline-that is, the said air, after having passed into the chamber G, will flow therefrom through the holes a, and into and up the space I), thence into and through the sponges t, and up through the partition H and into the space E, from whence, with the gasoline vaporized by it, it will flow through the sponge d of the extension F, out of which the carbureted air will be discharged by the pipe attached to the opening c, and leading to the burner or burners on which the said carbureted air is to be inflamed for the purpose of illumination or heat.

The excess of the air so carbureted will flow into the aerometer and gas-holder G, where it will'be stored for use, such aerometer serving also to equalize the pressure of the gas or carbureted air at the burners.

I would remark that the sponge d in the extension F serves to catch and retain the condensed gasoline, which usually flows back from the conduit while the apparatus is in use, or after the flame of its burner or burners may have been put out. This gasoline, by being suspended in the said'sponge, is in a situation to be vaporized by the next current of air which may be caused to flow through the sponge.

the sponge-chamber D, the perforated partition H, and the space E. r

2. The combination of the sponge d and the extension F with the chambers E and O, and the sponge t and the partition H, made and arranged in manner and so as to operate as specified. v
